Quiet day on 28 MHz - Wed 8th Apr 2020

Wednesday 8th April 2020. This was a quiet day on 28 MHz with just four stations heard on FT for the whole day.

095215 -14 -0.1  959 ~  CQ PA9CC JO32
102430 -15 -0.2 2009 ~  CQ DJ5JD JO33
121145 -20 -0.3 1165 ~  CQ EA5AD IM87
153530 -12 -0.2  622 ~  CQ PD2WL JO22

The Geomagnetic Kp index was at 2-3 for most of the day which isn't good for Sporadic-E. Some of the signals heard may well have been from meteor scatter as only there was only one decode from each of the stations.

Opening to Algeria and Saudi Arabia on 28 MHz - Tues 7th Apr 2020


Tuesday 7th April 2020. This was one of those days where there was hardly a murmur out of the radio on the FT8 frequency on 28 MHz yet there were still a good number of stations recorded.

Most of the 59 stations heard were probably via Sporadic-E although it's heard to be sure about HZ1SK in Saudi Arabia as that could have been multi-hop Sp-E or F2.

As we move further into April, we should start seeing more Sporadic-E openings.

Small opening on 28 MHz - Mon 6th Apr 2020


Monday 6th April 2020. Another quiet day on 28 MHz with just a few FT8 signals via Sporadic-E from Europe.

When is the next sunspot cycle likely to start???


As we bounce along the bottom of the sunspot cycle in the Spring of 2020, the big question now is when will cycle 24 end and when will cycle 25 begin? We won't know for sure until we have gone past the minimum and we look back but the chart above provides some clues.

The chart compares the duration of solar cycles 21 to 24 and as you can see, 24 has already gone beyond cycles 21 and 22 as of the start of April 2020.

The end of sunspot cycles 21 to 24 are shown in more detail below...

As of the start of April 2020, cycle 24 has gone about 10 months further than cycle 22 and 4 months further than cycle 21. On the other hand, it is still about 7 months shorter than cycle 23.

Back in December of 2019, a NOAA/NASA Solar Cycle prediction panel said that a solar minimum would occur in April of 2020 +/- 6 months.

Considering that the 'April 2020 minus 6 months' has now passed, we are now into the 'April 2020 plus 6 months' timeline. Surely we are very close to the minimum now if not at it?

Modest day on 28 MHz - Fri 3rd Apr 2020

Friday 3rd April 2020. There was hardly a murmur from the radio on the FT8 frequency on 28 MHz for most of the day except for  two local stations.

However, the band came to life in the evening with an opening to Gabon in central Africa, St. Helena in the South Atlantic, the Canary Islands, Brazil and Argentina.

There was a signal from Spain around this time so perhaps a Sporadic-E hop to the south from my location helped out.

In two to three weeks time, things should improving a lot as we head into the Sporadic-E season.

Thursday 2nd April 2020. There was a modest opening on 28 MHz today but most of the FT8 signals were buried in the noise.

Experiments with Slow Scan TV apps

Every Tuesday evening, we have a local net here in Cork on the VHF bands. This follows the following pattern... 1st Tuesday of the month (2m), 2nd Tues (70cms), 3rd Tues (4m & 6m) and 4th Tues (Digital).

On some months, there is a fifth Tuesday and we decided to use this for experiments.

For the 5th Tuesday in March of 2020, we decided to experiment with the Slow Scan TV apps for a smartphone. I was expecting that we would spend most of the first evening just downloading the various apps and trying to get them to work but it ended up being suprising easy.

The first thing we had to do was to download a SSTV decoder for the Google Play store and I think we all used Robot36 as shown above.


For sending SSTV signals, we used the SSTV Encoder app as shown above.

For the tests, we sent and received the signals on 145.475 MHz FM between members of the group and we each just held our mobile phones up to the loudspeaker and microphone of our radios.

The apps were very easy to use and we had them up and running in minutes. Using the 'Martin 1' SSTV mode, I sent out test transmissions and Don EI8DJ, Robbie EI3GGB and Jim EI8GS all successfully decoded the signals.


The photo above shows the signal that Robbie, EI3GGB decoded. The transmissions decoded by Don, EI8DJ are shown below.


Jim, EI8GS also reported successful decodes of the signal.

The original photos of the Daffodils and Gorse bush are shown below...


Obviously the quality could be better but this was our first attempt without experimenting about with audio levels for transmit or receive. The beauty of using a smartphone is that there are no wires. You just hold the phone up to the loudspeaker and it decodes the signal.

No doubt we will return to the SSTV app on another night to try and improve on the signals and picture quality. We were all agreed though that it was something new and novel to do and it was interesting to try something new.

It also struck me that this would make for an interesting activity for any club or group to try. Just go to the Google Play store and download the apps for free.

Quiet day on 28 MHz - Wed 1st Apr 2020

Wednesday 1st April 2020. This was a quiet day on 28 MHz with just four stations heard on FT8.

The two signals from the Netherlands and France may well have been via meteor scatter.

The two stations in NW Wales are probably direct via tropo.

Small opening to 28 MHz - Tues 31st March 2020


Tuesday 31st of March 2020. The FT8 frequency on the 28 MHz band was eerily quiet all morning with just one signal from Poland heard. Note that the lack of Sporadic-E signals may have been because the Kp index was at 4. i.e. There was a disturbance in the earths magnetic field.

A high K index is normally associated with poor Sporadic-E conditions.

Things seemed to improve in the evening with a modest opening to Brazil.

Opening on 28 MHz - Mon 30th March 2020


Monday 30th March 2020. I had the radio on in the background all day and it seem pretty quiet with only a few FT8 signals on 28 MHz audible. It was a suprise at the end of the day when the PSKReporter map showed that I had heard FT8 signals from South Africa, Chile and Europe.


It certainly wasn't an extensive opening and the map above really shows an accumulation of stations heard during the day gradually building up to populate the map.

At one stage when the FT8 signals were about S3 which seemed to be the strongest, I had a listen on the beacon part of the band and heard the German DL0IGI/B and DK0TEN/B beacons.

A total of 43 stations were heard. This is a list of the stations heard in order of distance...

Minor opening on 28 MHz - Sun 29th March 2020

Sunday 29th March 2020. This was one of those days where the FT8 frequency on 28 MHz seemed pretty quiet with just low level signals heard on the band.

The signal levels were so low that I didn't even bother scanning for beacons. I was actually suprised that there was some nice DX buried in those weak signals.

As the map shows, there was a low level Sporadic-E opening to the south of Spain and this no doubt coupled into some F2 propagation to Canary Islands, St.Helena Island and Brazil.

These are the 37 stations heard in order of distance...

Opening on 28 MHz - Sat 28th March 2020


Saturday the 28th of March 2020 was pretty similar to the previous day with a Sporadic-E primarily to Spain and Italy with some more DX further afield.

Nice to see St.Helena in the South Atlantic making it though as well as South Africa, Brazil and Israel.

This is a close up of the European stations heard on FT8 on 28 MHz...


The band was open to Spain for most of the daylight hours with some smaller openings to Italy as well.

It's worth noting that the PSKReporter website seemed to be down at times during the day so I'm not sure if all of my reports were uploaded?

These are the beacons heard on cw...

EI7GL 28240.0 IZ8RVA/B 15:45 28 Mar IO51TUJN70LI Italy
EI7GL 28194.0 IW4EIR/B 13:53 28 Mar IO51TUJN54AS Italy

EI7GL 28321.5 IZ1KXQ/B 13:34 28 Mar IO51TUJN54AC 0.1w Italy

The number of Italian beacons heard is more of a reflection on the smaller number of beacons in Spain.

It's interesting that for the last week or so, there have been plenty of Sporadic-E openings to say Spain and Italy but there has been very little to the Nordic countries or the Baltic states. There does seem to be fewer openings the further north you go.

A total of 282 stations in 25 countries was heard.

This is a list of stations heard in order of distance...

Looking at the German 28 MHz beacons heard in 2019


During the months of April, May and June of 2019, I did many scans of the 28 MHz beacon band from about 28.160 to 28.340 MHz. This post is about the number of days that I heard one of the beacons in Germany.

The map above shows the distribution of 28 MHz beacons in Germany. Note that the DB0BER beacon near Berlin was off air during the period I was monitoring so it is not included in the data below.

The chart below shows the number of days in 2019 that I heard a German beacon on 28 MHz...


1) DL0IGI with its 50 watts into a vertical antenna was heard on 35 days and is easily the most consistent German beacon here in Ireland.

2) DL0UM has just 4 watts into a vertical dipole and was heard on 26 days. Like DL0IGI, it is about 200kms further away from me compared to some of the other beacons and perhaps the slightly longer skip distance made a difference?

3) DB0MFI (9w GP), DK0TEN (10w GP) and DB0TEN (2w GP) were all about the same mark with 22, 21 and 20 days respectively. (Note - GP is a ground plane vertical antenna)

4) DF0ANN (5w dipole) and DM0AAB (10w GP) at 16 and 14 days were noticeably behind. Was it just pure chance or was there a reason?

5) DB0FKS was heard on just 8 days but this can be easily explained due to the fact it has just 1-watt into a small DV-27 vertical antenna (i.e. a loaded mobile whip).

In terms of distance, the German beacons are about 1,200 to 1,500 kms from my location in Ireland.


In conclusion... The reason I collected this data was to see if there was any unusual findings.

a) Was there a difference in the number of days heard between North and South Germany? The answer seems to be no.

b) Did distance matter? Maybe but the evidence isn't that strong. I seemed to hear beacons at 1,200kms as often as ones at 1,400kms.

The main factor determining what I heard from my location in Ireland seems to be just power and antenna performance of the beacons. 

German 28 MHz beacons... These are the current ones as of the end of 2019

28.205 MHz - DL0IGI - JN57MT - 50w Vert
28.210 MHz - DB0FKS - JN49IT - 1w DV27 GP
28.245 MHz - DB0TEN - JO42UV - 2w GP
28.257 MHz - DK0TEN - JN47NT - 10w GP
28.265 MHz - DB0ANN - JN59PL - 5w Dipole (Used to be DF0ANN)
28.273 MHz - DB0BER - JO62QL - 5w
28.278 MHz - DM0AAB - JO54GH - 10w GP
28.279 MHz - DB0UM - JO73CE - 4w Vert Dipole
28.285 MHz - DB0MFI - JN58HW - 9w GP


Methodology notes...
1) The equipment used for reception was a Kenwood TS690 transceiver with a vertical half-wave antenna. The take off to the east towards Germany is good with no obstructions.
2) I usually scan the beacon band on 28 MHz once I hear FT8 signals at a reasonable level that are easily audible. i.e. I know for sure the band is open.
3) All beacons must be positively identified before I post them on DXMaps which in turn puts them on the DX Cluster.
4) The mode of propagation for all signals heard was Sporadic-E.

More Sporadic-E on 28 MHz - Fri 27th March 2020


There was a reasonable Sporadic-E opening on Friday the 27th of March 2020 with signals from Italy and Spain mainly been heard.

In terms of DX, TR8CA in Gabon, 9G1SD in Ghana and HZ1SK in Saudi Arabia were heard.

This is a map of the opening to Europe in more detail...

Modest Sporadic-E opening on 28 MHz - Thurs 26th March 2020


Despite what the map above might suggest, Thursday the 26th of March 2020 was one of those days where the 28 MHz seemed to be just about open. I could hear signals for most of the daylight hours from Spain and Italy but it felt as if the MUF (Maximum Usable Frequency) was just above 28MHz.

During the day, it felt like the actual footprint of the Sporadic-E was pretty small allowing only a small number of stations to come at any one time.

This idea of a small footprint ties up with the fact that I only heard one beacon all day despite several scans.

EI7GL 28227.4 IW3FZQ/B 15:21 26 Mar IO51TUJN55VF Italy

The small footprint might also have been the reason for a lack of stations heard outside of Europe as the small area covered didn't line up with the paths to any DX stations when there was F2 propagation about.

In total, 167 stations were heard during the day which isn't bad for late March.

Another big opening on 28 MHz - Wed 25th March 2020


Wednesday the 25th of March 2020 was pretty similar to the previous day with a widespread Sporadic-E opening on the 28 MHz band even though it is still only late March.

As the map shows above, a very large number of European stations were heard. Signals from South Afrcica and Gabon were also heard as well as  Qatar and Kuwait in the Middle East. Unusual European ones were Georgia and Crete.

It's hard to tell whether the signals from Greece and Turkey were double hop Sporadic-E or F2.

I expected to hear some signals from South America but I heard nothing.

This is the map of European stations heard...


Some points...

1) Short Skip... There seemed to be less short skip compared to the previous day.

2) Scandinavia... Like the previous day, there were no openings to Norway, Sweden, Finland or the Baltic states.

3) Maritime Mobile... One unusual station heard was UR7FM/MM on a ship near the Straits of Gibraltar.

4) Beacons... These are the beacons that were heard...

Big opening on 28 MHz on Tues 24th March 2020


Tuesday the 24th of March 2020 was a really good day on 28 MHz with an extensive Sporadic-E opening on the band.

The FT8 signals heard on the band are shown above. In total, 764 stations and 39 countries were heard which was just like a day in June was like a day in the June at the peak of the Sporadic-E season.

As well as a large number of signals from Europe, Lebanon, Israel, Western Sahara, St. Helena Island in the S Atlantic, Columbia, Brazil and Argentina was also heard.

I also heard TT4AM in Chad on cw.

This is the map of European stations heard...


As you can see, there was quite a concentration of stations from Italy, Spain, Germany and France.

Some notable features of the maps are...

1) Missing... Nothing heard from Norway, Sweden, Finland or the Baltic states.

2) Short Skip... Quiet a few signals from Brittany which is about 600kms from me. This is normally in the Sp-E skip zone and is hard to hear.

3) Numbers... The large number of stations heard was probably helped by the fact that countries like Spain, France and Italy are in lock down due to the Corronavirus epidemic. However, it was still exceptional for the end of March.

4) Double-Hop... You can see from the map where my one-hop Sporadic-E limit of about 2,200 kms is. There is a sudden drop of of stations in Southern Italy and Eastern Poland. The signals from places like Greece, Bulgaria, Romania and Turkey were probably double hop.

5) High MUF... It looks as if the 50 MHz band was open as well and they are report of Band 2 radio stations from Spain and France being heard in the northern part of Ireland. The maximum usable frequency reached at least 100 MHz.

Normally I just leave the radio monitoring the FT8 frequency and check the PC occasionally to see if anything was heard. As I could see the signals were reading 'S9' at times, I tuned around the band as well for beacons and this is what I heard...

F5ZEH/B in Brittany is an unusual one as it's normally in the skip zone and I think I have only heard it a few times.

SV6DBG/B in Greece was probably double hop Sporadic-E.

IW4EIR/B was a new one for me. According to QRZ, it's a 1.5-watt beacon. Looking at the DX-cluster, there are no spots for this beacon between May 2018 and December 2019 so I presume it was off air for 18 months.

I spent about two minutes listening around the SSB part of the band and there seemed to be plenty of activity although to be honest, I was bored after the two minutes.

On the CW portion of the band, I heard TZ4AM in Mali working a pile up split.

Overall, a really good day on the 10-metre band considering it was the end of March at the bottom of the sunspot cycle.
